  Hi,
    if we run simple programs with single process
(mpirun pgm -np 1) on SIGNGLE m/c, the prg takes less time. If I run with MANY processeson SINGLE m/c, it will take more time as compared to 1 process.  Actually, the time should be less if we run with multiple proceses. Why it is so ?
  thanx in advance.
bye.
